Kristoff has played Neil Winters on 'Y&R' since 1991 -- a role that earned him 9 Daytime Emmy Award nominations. He also won 10 NAACP Image Awards.

Kristoff has a tragic and troubled history with suicide. He and his ex-wife, boxer Mia St. John, lost their son, Julian, when he took his own life in 2014, while getting treatment at a mental health facility. Mia and Kristoff sued the facility for negligence. The suit was eventually settled.

In 2017, around the anniversary of Julian's suicide, Kristoff threatened to kill himself with a gun. Cops placed him under a 72-hour hold for psychiatric evaluation.

Mia reacted to Kristoff's death with an emotional post on social media (which she has since deleted), and it's clear she is connecting his death to Julian's. She wrote, "THAT HOSPITAL KILLED OUR SON @TheArtofJulian THEN MY HUSBAND @kristoffstjohn1. THATS WHAT HAPPENED! THEY KILLED MY FAMILY"

R.I.P...Totally unexpected..I read he was still in a lot of pain over losing his son...I always liked him.. I also remember seeing him on the TV sitcom "Charles & Co." with Gladys Knight and Flip Wilson.
